I went into safe mode, replaced the defective regsvr32.exe with a good copy, and then rebooted normally. The file was again replaced with a zero byte file immediately after the system had completed rebooting.
After checking different sources on the Internet, I thought it MIGHT be a Norton system application that I have installed on my system for virus and firewall protection. However, I found out that this is NOT the case since my sonís PC had the identical problem and I rebuilt his machine up from a formatted system disk, reinstalled Win 2K and the associated Norton applications. His regsvr32.exe file is now fine, so I know I have some type of virus.
I have tried several different types of virus scanners, Spyware Doctor, Avast, etc., but none of them can identify the problem.
Is there any way to track who/what made modifications to a file?
Can you help me?
